The first section of the pipe I is slipped into the coupling cap or box II for the head or flange I to lie in such box, and the coupling box or cap 11 is screwed onto the neck 0, with the gasket between the flange I and neck 0, attaching the first section of the pipe I in line with the passage '2'. The outer end of the first section of the pipe I has screwed thereto a shell or casingJby one of the necks J for thepassage in the tube orpipe I to be in line with the side passage j. The connection or tube L is screwed into the neck J for its passage Z to be in line with the passage j, and,if desired, a gasket may be used to make atight joint in the neck J. The coupling shell or box M, which has been slipped onto the connection or tube L before entering such tube into the neck J", is screwed onto the neck N of the first sirup-can O, with the gasket m between the flange I/ and the neck N, completing the connection of the first sirup'can to the tube or pipe I, and the next section of the tube or pipe I has one end screwed into the first shell or casing J, and the second shell or case J is attached to its other end bya neck J, and this shell or case is attached to the second sirup-can, as described, for the connection of the first shell or case with the first sirup-can, and other sections of the pipe I are attached and connections made with the other sirup-cans in the same manner until all the sirup-cans are connected. The pipe S from each sirup-can is attached to the neck R of this can by the coup ling box or cap S, and such pipe is led to the discharging-point, and the sirup-cans are placed in the receiver or boX U on the shelf D or suspended in such receiver or box in any suitable manner, and with the fountain A charged the dispensing apparatus is ready for use, the sirup-cans havingbeen filled with the desired sirup by unscrewing the cap or cover Q and filling the can through the mouth or opening P, and when filling the can the plug-valve K is turn ed so as to close the opening or passage j, as shown in Fig. 8.

In use the valve 6 is opened for the charged water or other fluid to pass from the fountain A through the tube B, passage b,port Z), passage Z), passage g, and tube G to the draft cock or valve, and the valve d is open for gas in the upper part of the fountain A to pass into the passage a, port ct, passage a", and passage i 'into the tube I, and when the plug-valve K is turned as shown in Fig. 4 this gas will enter each sirup-can through the passages j, j, Z, and n, and such gas will produce a pressure in the sirup-can, by which the sirup will be forced into the tube S and can be drawn from such tube at the discharge end into a glass or tumbler, as usual, and for discharging into the glass or tumbler each pipe S is provided with a cock or other suit able device to govern the flow of the sirup. The dispensing of the soda or aerated water is essentially the same as any other forms of apparatus, the tumbler being placed in position to receive the desired sirup, which is discharged thereinto from the tube S, after which the tumbler isplaced beneath the soda-water discharge and the water or other fluid turned thereinto.

The valves K, controlling the flow of the gas from the pipe I into each sirup-can, are constructed, as shown in Figs. 3 and i, so that by turning the valves as shown in Fi 3 free communication is had between the pipe I and each sirup-can for the gas to enter the cans, and by turning the valve into the position shown in Fig. 3 the discharge-passagej' is closed, and no gas will pass into the sirupean, and when in this condition the cap Q can be removed and the can filled with sirup without removing the can from the box or re ceiver U, and when filled the cap Q is screwed on and the valve K turned as shown in Fig. 4, when the sirup-can is again ready for use to discharge the sirup by the pressure of the gas through the pipe S.

The sirups have heretofore been dispensed or discharged from ordinary bottles or from sirup-cans or jars placed in boxes and drawn into tumblers by means of cocks or other appliances, using gravity as the dispensing means, and the water or other charged fluid has been drawn by means of a tube extending downward to the point in the fountain near the bottom, so that with the pressure of the gas in the fountain the water or other fluid will be forced to flow through the inserted tube to the discharge-point, and this gas in the fountain always lies at the top of the fountain.

The presentinvention consists, essentially, in utilizing this gas for forcing or driving the sirup from the can, thereby enabling the can to be located below the drawing-point and in an ice-box or other receiver where it is readi y accessible, and this end is accomplished by connecting each sirup-can with the upper portion of the fountain, so that gas can flow from the fountain and enter the sirup-can, and such connection can be had in the manner shown or by means of other devices which will attain the same end, and this gas admitted to each sirup-can will occupy the space at the top of each can and exert a pressure by which the sirup will be forced from the can.

The communication of the sirup-can with the gas-supply pipe is one which enables each can to be shut off whenever desired for filling or other purposes without interfering with the dispensing of the sirup from the other cans, as when the valve is turned to shut off one can the opening or passage 7c is still in line with the opening or passage j, allowing free communication through the whole length of the pipe I.

The locating of the sirup-cans in a box or receiver enables the sirup to be kept eonstantly cool, as the box or receiver can be supplied with iee or other cooling medium, and at the same time the sirup-cans are located IOC IIR

where they are readily accessible for fillingor other purposes, so that they can be'refilled without removal.

The invention can be used for dispensing either cold or hot soda or other aerated or charged waters, and if used for drawing hot soda the carbonated gaspassing into the sirup cans or jars will charge the sirup in such cans or jars, and the charged soda will be drawn into the tumbler, and hot water from any suitable heater can then be turned into the sirup, or the sirup will be dispensed into hot water, and in either case the drink will be hot and will be charged with the aerated or carbonated sirup' or fluid, forminga drink essentiallythe sa'measthat drawn with cold watendfiering in this respect from the so-calied' hot soda now dispensed, in which nothingmore is had than hot water ponred'or mixed with a sirup, and this mixture is-dispensed ashot soda, while in fact no aeration is had therein.

The fountain A is to be chargedasusual, and where a'compact apparatus'is required the fountainand. jars can be located in one boX'or receiver, or the fountain can be located outsideof the box'orreceiver for the. sirupcansat any point desired, the pipe I for the sirup-cansextending to the fountain, so that thecarbonated gas from the fountain can be used'to dispense the sirup from thejar.

The headfor discharging the gas and fluid instead of being'a single head with two passages, one for the gas and one for the fluid, could be a single head Witha' passage forthe gas-and a single head for the passage of the 'fiuid, each head having a valve for closing the passage, and where it. is desired to dispense sirup from a fountain without-dispensing the water or'ot-her fluid from the same fountain a headlcan be providedhaving. only a'venting-passage for the gas, with'a valve controllingisuch passage and a pipe connecting the head withthe sirup-jars, as shown, or inany other suitable'manner that will furnish'a connection by which the pressure of the gas can be utilized to discharge the sirup andthe gas shut off from a jar when desired for filling the jar or for other'purpose.
